Senior Frontend Engineer · Avenue Code

Alexandre Mendes

I design frontend platforms and bring AI agents into how they are built, tested and reviewed.

Frontend platforms, built with AI

Frontend engineer since 2015, working on enterprise web platforms: component frameworks, micro-frontend architecture, test strategy and security remediation. Today most of my work is about making AI a reliable part of the engineering loop, not a side tool.

How I work with AI

I use AI agents as part of the engineering process, with the same quality gates as any other contributor.

Agentic development workflows

Claude Code agents and skills that run tests, lint and builds, open commits and pull requests, and keep the noisy output out of the main session.

AI-assisted testing

Agents that write and maintain unit and end-to-end tests, aimed at full coverage from the bottom of the component tree up.

Multi-model code review

Two independent reviews of the same diff, from different models, merged into one report so disagreements get a closer look.

Model Context Protocol

Connecting agents to real tools and data through MCP servers, from API documentation to image generation.

ZL.js

An open-source, AI-first frontend framework.

Every enterprise frontend team starts the same way: it assembles a component library, an application framework, state management and a styling system, makes them work together, and then customizes the result from scratch, each with its own mistakes and its own quality rules.

ZL.js joins the steps every team repeats (integrate the stack, customize it, verify it) in one open pipeline driven by an AI agent that works from a tested component library, with quality rules enforced from the first commit.

available

  • Tested React component library, documented in Storybook
  • Conversational agent that composes interfaces from natural-language prompts
  • Quality kit with shared lint, format and commit rules

roadmap

  • Agent that composes interfaces only from library components
  • Agentic project bootstrap with the integrated stack and quality kit
  • Security checks on dependencies and known vulnerabilities before release
